JOSEPH HIGBEE, OF BLOOMFIELD, IOIVA.

LOCK.

SPECIFICATION forming part of Letters Patent No. 449,677, dated April'7', 1891.

Application filed August 18, 1890- Serial No. 362,846. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH HIGBEE, a citizen of the United States,residing at Bloomfield, in the county of Davis and State of Iowa, haveinvented a new and useful Improvement in Locks, of which the followingis aspecification.

My invention has relation to that class of doors which it is foundnecessary or desirable to secure and lock in two or more places.

My object is to provide a lock which shall be adapted for actuating twoor more bolts from one and the same point by one and the same movementof one and the same key.

My invention consists in an engaging-lug, which is caused to travel in acircular path by means of the key, which lug is adapted to impinge, whentwo bolts are employed, against a concaved face formed on one bolt, saidbolt being acted upon by yielding pressure, and in its further travel toimpinge against a like concave face formed on the other'bolt, which alsohas bearing against it yielding pressure.

My invention consists furtherin certain details of construction andarrangement of parts hereinafter to be more fully described, referencebeing had to the accompanying drawing, in which the figure is a sideview of a portion of a door and the doorway jamb and sill, the jamb andsill being broken away, the improved lock being shown in position as inuse, and the face-plate being removed to show the interior.

A indicates the portion of door, B the portion of doorway-jamb, and Othe sill portion.

D D are bolts arranged, respectively, approximately in avertical andhorizontal plane and at right angles to each other, a portion of thelength of each of said bolts being within the boxing E of the lock.

Secured to the boxing of the lock on the interior thereof at the desiredpoints are the springs H IF, the spring H bearing against and upon thebolt D and the spring H bearing against and upon the bolt D J is atumbler adapted to admit a key, which may be of any desired kind, saidtumbler having a projecting lug j fixed on its perimeter.

. The bolts D D are each concaved at (Z (Z' on their edges.

When the key is inserted into the slot of the tumbler J, the latterbeing in the position shown in the figure the bolts being in a lockedposition and turned from the right to left, the lug j of the tumbler Jengages within the concave face (Z of the bolt D, and as the spring Hbears against the said bolt the lug in its further travel raises thebolt in avertical plane and releases it from engagement with the sill.In the further travel of the tumbler J, carrying its lugj, the latter engages within the concave d of the horizontal bolt D and the spring Hbearing upon the said bolt D causes the latter to be moved in ahorizontal plane and to be withdrawn from the jam. By this means theparts are unlocked. \Vhen desired to lock, the key is turned in thereverse directiomwhen the same operation takes place.

-I do not desire to be understood as confining myself to the number ofbolts shown, as a bolt could be arranged so as to be in a position to beoperated upon and lock the door at top.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a lock, the combination,with a box or case having bearings forbolts that are in a crossed position and two sliding bolts, each havinga concavein one of its edges or faces, and a tumbler having a lugadapted to enter the concaves of said bolts, in the manner set forth,for the purposes stated.

2. The combination,in a lock, of a plurality of bolts arrangedapproximately at right angles to one another, said bolts being adaptedto engage the doorjamb, sill, or top piece ofa door, respectively, atumbler with which the key of the lock engages to rotate the salne,.alug fixed to and projected from said tumbler, adapted to engage,respectively, concave faces or edges on each of the bolts in thecontinued rotation of the tumbler, and fixed springs which bearjuponeach of said bolts, as set forth.

JOSEPH HIGBEE.
